This invention relates to improvements in washing machines and has particular reference to means for converting an ordinary washtub into a washing machine.

A further object is to provide means whereby the water may be conducted to or away from the washing machine.

A still further object is to provide a mechanism which is simple in construction, economical to operate and one which may be readily installed without involving great expense.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, v

Fig. 1 is a vertical cross section of a washtub having my invention applied thereto, a portion of the agitator being shown in cross section,

Fig. 2 is a vertical cross section of my mounting mechanism, and

Fig. 3 is a top plan view of the gearing arrangement.

There are many forms of washing machines, upon the market adapted to be attached to the ordinary set tub. These, however, rely upon the agitating element dipping into the tub from the top, thus producing a plunger action. Applicant has, therefore, devised an arrangement whereby by providing a single-hole opening in the bottom of the set tub, a modern form of washing machine may beproduced, and one which will not injure the clothes, in counter-distinction to the injury caused by the beater type.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates any washtub of any desired shape or material. In the bottom of this tub I provide an opening 6, through which I thread a vertically disposed fitting l, and by referring to Figs. 1 and 2, it will be noted that this fitting is tapered so as to readily receive the agitator 8, which may be removed at any time when desired. This fitting has a hollow chamber D, which connects with passages I I and with the chamber I 2 formed in the fitting 13, which threadedly engages the lower threaded end of the fitting 1. A tubular extension I! is formed upon the fitting l3 and serves to guide the drive-shaft l6, which carries a squared end ll, which engages a suitable opening in the agitator 8. Packing material I8 is held in place by a gland nut IS. A driving gear'2l is engaged by a rack 22 reciprocated by an eccentric 23 mounted upon a gear 24, driven by a worm 26 through a belt 21 from the motor 28. A valve 25 mounted in the pipe II enables the user to draw the water from the tub by manipulation of this valve. It is also understood that water may be introduced into the tub in the same manner by reversing the flow through the pipe 3|.

It will thus'be seen that by securing my attachment to any washtub, the same will form a modern washing machine.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim 'In a device of the character described, the combination with a tub having a fitting extending through the bottom thereof, said fitting having a frusto-conical upper end extending into the tub a sufiicient distance to form a bearing, an agitator rotatably positioned on said fitting, a shaft extending through said fitting and connected to said agitator; a second fitting secured to said first mentioned fitting and contacting the bottom of said tub at a point below the tub and in axial alignment with said first mentioned fitting, said second fitting having a tubular shaft enclosing portion extending into said first mentioned fitting, passages formed in said first mentioned 40 fitting and said second mentioned fitting at a point outside the margin of said tubular member, whereby fluid may be drawn from the tub without engagement with said shaft.
